To all whom 63 may concern Be it known that L Joann Slwciiennne,

a subject? of the King of lrnssia, residingnt 11 Bechlehemkanal, rechts, Papenburg-cn the-Ems, Germany, have invented certain new and useful Improvements in and lie lilting ii) the Processes for Simmering Smelting Products and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention,

The present invention relates to improvements for sintering smelting-produces and similar materials especially fine granular ores, purple ores and line (lust such fine materials: living generally termed fines.

Up to the present time a drawback was experienced in sintcring finely divided, granular smelting product's for instance fine granular ores. purple ores and fine (lust,

The present invention avoids all these incouvunimiccs by adding sirani to the air forced through the materials to he sintcrcd. If these ore-materials are too fine or too dust-like l'or hring handled without injuring health the. same must he sprayed with weter-as is necessary according to the laws of at; least several conntrics--hefore being charged into the treating vessel or l'urnarc. -Th'is steam living employed in a suitably specification at Flatten Patent.

suilicicnt proportion is condensed the colder layers, consequently also in the upper layers of lhe materials so he sintered, so that a superficial inoistening of the upper layers of "the materials to be sinterecl will take place and thus prevent a senaraticn of the material to he sinterccl from i; ie parts of fuel. Part of the steam is also decomposed by the glowing (incandescent), perils of the fuel, so that: the Water gas formed will favorably promote at the same time by, its presence and high temperature of combustion the sintering and a further portion of the steam escapes as primed steam from the sintering receptacle or furnace, and is clearly visible as a cloud of highly primed steam issuing from the cover of the furnace.

In the drawing, showing a suitable form of furnace A is a cover connected to a suit.- ahle outlet fine a serving to conduct, the generator gas and excess steam from the furnace. This cover rests on a shallow sintering chamber or converter G, mounted by ,meansof trunnions on a suitable carriage K. This converter has a grate or rated. hottoni R beneath which air is adznitted through. pipe L and the steam through pipe D.
